This is a guide for the Basalt map in Counter-Strike 2 (CS2):

Map Name:
The map is named after Basalt, which is a type of volcanic rock that forms from the rapid cooling of basaltic lava exposed at or very near the surface of the Earth. Basalt rock columns are natural pillars of hardened lava created by the contraction of volcanic rock as it cools. They are often shaped like hexagons, pentagons, or octagons due to the cooling process and can form as vertical cliffs or terraced steps. It is usually dark in color (typically dark grey to black), fine-grained & dense, and rich in iron and magnesium with lower amounts of silicon, making it a mafic rock.
